About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-30
The AirTAC SAIJ200X95-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end during commissioning. With a 95 mm nominal stroke and a 30 mm adjustment range, this SKU provides a usable travel window of 65 to 95 mm without requiring external stops. It delivers massive thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa.
This heavy-duty actuator features a robust 40 mm piston rod made of SUS420J2 stainless steel (code A) for enhanced durability against lateral stress. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning of CMSE reed or DMSE electronic solid-state switches. Fluid must be filtered air, operating between 0.15 and 1.0 MPa within a -20 to +70 C temperature range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-30 Is Used
Heavy Press Changeover
Dial in the 65-95 mm travel window on the fly to accommodate varying material thicknesses in heavy-duty pressing operations without swapping cylinders.
Machine Setup Calibration
Use the rear stopper to fine-tune the exact end-of-stroke position during initial commissioning, eliminating the need to bolt on external mechanical stops.
Variable End-Stop Forming
Leverage the 15708 N push force at 0.5 MPa for large-scale metal forming, adjusting the cylinder's effective stroke by up to 30 mm for different product sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-30 the Right Cylinder?
Choose this 200 mm bore actuator when your application demands maximum pneumatic force and variable end-position tuning. If you need less thrust, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, while the 200 mm bore provides the highest output in the series. The adjustable stroke is ideal for machine setups requiring precise end-stop calibration during product changeovers. Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold a load without live air pressure. For fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. To match this exact ISO 15552 replacement, verify the 200 mm bore, 95 mm stroke, 30 mm adjustment, PT tapered ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-30 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 30 mm from the 95 mm nominal stroke, providing a usable window of 65 to 95 mm. It only sets the travel end and does not lock the load without live air pressure.
